Cisco Asr 9000 Series Aggregation Services Router Interface And Hardware Component Command Reference - Cisco ASR 9000 Series Command Reference Manual

Ethernet OAM Commands on the Cisco ASR 9000 Series Router
Examples
The following example shows how to display the information published in the Interface AIS table:
RP/0/RSP0/CPU0:router# show ethernet cfm interfaces ais
Defects (from at least one peer MEP):
A - AIS received
R - Remote Defect received
L - Loop (our MAC received)
C - Config (our ID received)
X - Cross-connect (wrong MAID)
P - Peer port down

The name and state of the interface.
The direction that the AIS packets are transmitted,
up or down.
The level of the lowest MEP that is transmitting
AIS.The field is blank if there are no down MEPs on
the interface, and AIS is being transmitted due to
configuration on the interface itself.
Defects detected by the lowest MEP transmitting AIS.
The levels of any MEPs on the interface that are
receiving AIS from a lower MEP, and potentially
re-transmitting the signal. If the highest MEP is not
re-transmitting the signal, the list of levels is ended
using an exclamation point.
The level at which AIS is being transmitted outside
of the interface, via a MIP. The field is blank if this
is not occurring.
The interval at which AIS is being transmitted outside
of the interface via a MIP. The field is blank if this
is not occurring.
If AIS is being transmitted outside of the interface,
the time that the signal started. The field is blank if
this is not occurring.
